实验研究了在电磁感应透明条件下，囚禁在一维光晶格中的冷原子的光子学性质。我们发现，这样的介质有两个光子带隙。其中之一是在透明窗口，并产生了布拉格镜，这是光谱非常窄，动态可调。我们讨论了这个系统的优点和局限性。作为一个可能的应用说明，我们展示了一个双端口全光开关。
We experimentally study the photonic properties of a cold-atom sample trapped in a one-dimensional optical lattice under the conditions of electromagnetically induced transparency. We show that such a medium has two photonic band gaps. One of them is in the transparency window and gives rise to a Bragg mirror, which is spectrally very narrow and dynamically tunable. We discuss the advantages and the limitations of this system. As an illustration of a possible application we demonstrate a two-port all-optical switch.
